SUMMARY

During this operating peritcd for Calvert Cliffs Nuclear Power

- Plant Units 1 and 2, a total of 705 analyses were performed on 637 environmental samples. In addition, 1100 thermoluminescent dosimeters (TLD's) were analyzed for ambient radiation exposure rates.

The samples collected from the aquatic environment included bay water, fish, oysters, and shoreline sediment samples. Bay water was analyzed for tritium and gamma emitters. Fish, oysters, and shoreline sediments were analyzed for ganna emitting radionu-clides.

Monitoring the atmospheric environment involved sampling the air

. , at various locations surrounding the plant. . Air particulates and gaseous iodine were collected on glass fiber filters and silver '

zeolite molecular sieve cartridges, respectively. The particu-

, late filters were analyzed for beta activity and gamma-emitting nuclides. The molecular sj eve cartridges were analyzed for airborne I-131.

Samples from the terrestrial environment included only vegetation samples, which were cc11ected and analyzed for gamma emitters and I-131.

Measurements of external radiation vere performed by . analyzing TLD's~from twenty-three locations surrounding the plant. ,

Low levels of variout man-made fission and activation by-products were observed in the environment surrounding the plant during the year 1987. Some of these observations were attributed to fallout from past atmospheric weapons testing. The others cited were related to the operation of the plant (viz., H-3, Co-58, and Zn-65 in bay water; Mn-54, Co-58, Zn-65, and Ag-110m in oyster samples; and Mn-54 in vegetaticn samples).

In order to assess the plant's . contribution to the ambient

- radiation levels of the surrounding environment, dose calcula-

. tions were performed using the plant's effluent release data, on site meteorological data, and appropriate pathways. The results of these dose calculations indicate:

a. a maximum thyroid dose of 3.81E-01 mren via liquid 1

b. a maximum whole body dose of 2.50E-01 mrem via ,

liquid and gaseous pathways which is about 1% of the acceptable limit of 25 mrem /yr as specified in 40 CFR 190;

c. a maximum calculated dose to all other organs via liquid and gaseous pathways was equal to 1.36 mrem from the GI tract and skin, respectively. This dose was about 5% of the allowable limit of 25 mrem /yr as specified in 40 CFR 190.

Thus it is concluded, based - upon the levels of radioactivity

operation of Calvert Cliffs Nuclear Power Plant Units 1 and 2

  • did not cause ar.y significant impact on the surrounding environment during the year 1987. .

B. INTRODUCTION I 1

Baltimore Gas and Electric Company (BG&E) has been conducting a radiological environmental monitoring program in the environs of i the Calvert Cliffs Nuclear Power Plant since the summer of 1970. i The Calvert Cliffs site is an operating nuclear generating station consisting of two pressurized water reactors. Unit 1 achieved criticality on October 7,.1974 and commenced commercial operation in May 1975. Unit 2 achieved criticality on November  ;

30, 1976 and went into commercial operation April 1, 1977. ,

Originally the radiological environmental monitoring program was )

conducted under separate Environmental Technical Specifications (24,25). On July 29, 1977 the monitoring program began operation i under a combined set of Technical Specifications (26). The I

, program has opeated as such until March 1, 1985 when the Environnental Technical Specifications were revised to reflect a new generic format for radiological environmental monitoring l

, adopted by the Nuclear Regulatory Commission (27). Changes in 1 the program (aample locations, sample types, and/or sampling frequencies) have been implemented to conform with these revisions.

Results of the monitoring program for the preoperational and previous operational periods through December 31, 1906 have been '

reported in a series of documents (1-23).

Results of the monitoring program for the current operational ,

period of January 1, 1987 through December 31, 1987 are included l In this report. The report presents the content of the '

Radiological Environmental Program (Table 1), the sampling ,

locations (Appendix A), the summary of the analytical results of I 1987 (Table 2), a compilation of the analytical data for 1987  ;

(Appendix B) , the results of the EPA Intercomparison Program and '

the Quality Assurance Program (Appendix C) , and the results of the Land Use Survey (Appendix D). Interpretation of the data and conclusions are presented in the body of the report.

The envi*onmental curveillance data collected during this reporting period were compared with that generated in previous periods whenever possible in order to evaluate the environmental' radiological impact of the operation of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during the year 1987.

1 January 1 - December 31, 1987 Docket Nos. 50-317/318 C. PROGRAM C.1 Obiectives The objectives of the radiological environmental monitoring program are:

a. To determine whether any statistically significant increase occurs in the concentration of radionuclides in important pathways,
b. To detect any measurable buildup of long-lived radio-  ;

nuclides in the environment, I

c. To monitor and evaluate ambient radiation levels,
d. To verify that radioactivity and ambient radiation levels attributable to plant operation are within the limits i specified in the Technical Specifications (27) and the  !

Environmental Radiation Protection Standards as set forth .

I in 40 CFR Part 190. ]

C.2 Sample Collection .

The location of the individual sampling stations are listed in Table A-1 and shown in Figures A-2 and A-3. All samples were collected by contractors to, or personnel of, the Baltimore Gas and Electric Company according to BG&E Operating Procedures (28). ,

Radiochemical analyses were performed by BG&E in accordance with I established laboratory procedures (30).

C.3 Data Interpretation i It is the characteristic of environmental monitoring data that l many results occur at or below the minimum detectable level i (MDL) . In this report, all results at or below the relevant MDL I are reported as being "less than" the MDL value. 1 C.4 Procram Exceptions  !

The air sampler with sample code Al and the thermoluminescent dosimeter with the cample code DR7 had been incorrectly located at the time when the new Environmental Technical Specifications were first put into effect (March 1, 1985). The matter was I corrected on May 19, 1987 and May 31, 1987 respectively, when both were moved to a site 0.7 kilometers south of the plant (see Table A-1 for site description).

January 1 - December 31, 1987 Docket Nos. 50-317/318 D. RESULTS AND DISCUSSION All the environmental samples collected during the year were analyzed using BG&E's laboratory procedures (30). The analytic results for this reporting period are presented in Appendix B and also summarized on an annual basis in Table 2. For the purposes of discussion, the analytical results are divided into four categories. The categories are the Aquatic Environment, the Atmospheric Environment, the Terrestrial Environment, and Exter-nal Radiation. These categories are further divided into subcat-egdries according to sample type (e.g., Bay Water, Aquatic Organisms, etc. for the Aquatic Environment) . l l

D.1 Acuatic Environment The aquatic environment surrounding the plant was monitored by analyzing samples of bay water, aquatic organisms, and shoreline sediment. These samples were obtained from various sampling locations on the Chesapeake Bay near the plant.

D.1.a Bay Water Monthly bay water samples were taken from two locations during the year. These locations are the Intake Area (sample code Wal) and the Discharge Area (sample cedo Wa2). The samples were obtained from a composite sampling system operating at each location for the entire sampling period. These samples were analyzed for tritium and gamma emitters.

The tritium analysos, performed on quarterly composites of the l monthly bay water samples, showed only two detectable concentra-  !

tions of tritium. Both of these positive results were observed in samples obtained from the Discharge location (Wa2) during the second and fourth quarters of the year. The results were 477+/-134 and 271+/-149 pCi/1, respectively. Both concentrations are similar to the results observed in both the preoperational (6) and previous operational periods (7-23).

Monthly analyses for gamma emitters exhibited detectable concen-trations of two activation products, which are related to the operation of the plant. Zinc-65 was observed in the April Intake sample (Wal) at a concentration of 4. 6+/-3. 3 pCi/L, and Co-58 was observed in the April Discharge sample (Wa2) at a concentration' of 10+/-3 pCi/L. Both of these radionuclides have been observed in this sampling medium during previous operating periods (7-23) at levels similar to the current ones.

January 1 - December 31, 1987 Docket Nos. 50-317/318 .

D.1.b Acuatic Orcanisms Samples of aquatic organisms were obtained from four locations during the year. Samples of fish, when in season, were taken from the Inthke Area (sample codes Ia1 and Ia2) and from the Patuxent River (sample codes Ia4 and Ia5). Oyster samples were obtained quarterly from Camp Conoy (sample code Ia3) and Kenwood Beach (sample code Ia6). Edible portions of these samples were analyzed for gamma emitters.

Gamma spectrometric analyses of the fish samples from both lodations exhibited a single detectable concentration of Cs-137 (11+/-8 pCi/kg) in a sample of Weakfish collected form the Intake (Ia2) during the month of September. The presence of this radionuclide is most probably due to fallout from past nuclear weapons testing.

Quarterly analyses for gamma emitters in oyster samples, showed detectable concentrations of plant-related radionuclides. .

Manganese-54 was detected in the third quarter sample collected from Camp Conoy (Ia3) at a concentration of 9+/-7 pCi/kg, and Co-58 was observed in the second and third quarter samples from .

the same sampling site at concentrations of 25+/-8 pCi/kg and 18+/-10 pCi/kg respectively. In addition Ag-110m, ranging from 87+/-12 pCi/kg to 115+/-16 pCi/kg, was observed in all samples collected from that site during the year. It was also observed in the fourth quarter sample from Kenwood Beach (Ia6) at a concentration of 18+/-10. And lastly, 2n-65 was observed in the fourth quarter sample from the control location Ia6 at a concen-traticn of 28+/-15 pCi/kg. The presence of these radionuclides and their concentration levels are typical of that observed in previous operating periods (7-23).

D.1.c Shoreline sediment Semiannual shoreline sediment samples were taken from one loca-tion during the year. This location is the shoreline at Camp Conoy (sample code Wbl). The samples obtained from this location were analyzed for gamma emitters.

Gamma spectrometric analyses of these samples exhibited no detectable concentrations of any fission or activation products.

D.2 Atmospheric Environment The atmespheric environment was monitored by analyzing air particulate filters and silver zoolito cartridges (for trapping radiciodine species). These samples were collected from various locations surrounding the plant.

D.2.a Air Particulate Filters Weekly composite air particulate filter samples were collected from five locations during the year. These locations are On Site (sample codes Al(OLD) and Al (NEW) --see section C.4 Program Exceptions and Table Al in Appendix A for an explanation of this sample coding), Camp Conoy Road Near the Emergency Siren (sample code A2), Bay Breeze Road (sample code A3), Lusby (sample code A4), and at the Emergency Offsite Facility (sample code A5).

These samples were analyzed for beta activity and gamma emitters.

Weekly analyses for beta activity on air particulate filters collected from all five locations showed values charateristic for background (7-23),

i Gamma spectrometric analyses of monthly composited air parti- '

culate samples exhibited no detectable concentrations of any fission or activation products in any of these samples. (

D.2.b Air Iodine i Weekly composited silver zeolite cartridges (for trapping radiciodine species) were collected from five locations during ,

the year. These locations are On Site (sample codes Al(OLD) and Al(NEW)--see section C.4 Program Exceptions and Table A-1 in l Appendix A for an explanation of this sample coding), Camp Conoy  !

Road Near the Emergency Siren (sample code A2) , Bay Breeze Road  !

(sample code A3), Lusby (sample code A4), and at the Emergency Offsite Facility (sample code AS) . These samples were analyzed for radioiodine species. ,

Weekly radioiodine analyses of silver zeolite cartridges collect- i ed from all five locations exhibited no detectable concentrations of I-131 in any of these samples. i t

D.3 Terrestrial Environment The terrestrial environment was monitored by analyzing samples of vegetation collected monthly, when available, from various samp-ling locations near the plant.

i D.3.a Veaetation  !

Vegetation samples were collected from three locations during the i

l year. These locations are Bay Breeze Road (sample codes Ibl, j Ib2, and Ib3), On Site Before the Entrance to Camp Conoy (sample.  !

codes Ib4, Ib5, and Ib6), and the Emergency Offsite Facility 1 (sample codes Ib7, Ib8, and Ib9). These samples were analyzed l for gamma emitters, including analyses for I-131.  !

Gamma spectrometric analyses of these samples revealed the presence of only two man-made radionuclides. Manganese-54 was observed once in the October collards sample collected from the garden at Bay Breeze Road (Ib3). The concentration of this radionuclide was 8+/-8 pCi/kg. Cesium-137 was observed sporadi-cally during the year in samples obtained from the garden situat-ed before the entrance to Camp Conoy (Ib4,5,6). The concentra-tien of this radionuclide ranged from 9+/-9 pCi/kg to 77+/-21 pCi/kg. The presence of Mn-54 is probably attributable to the operation of the plant, while the presence of Cs-137 to past atmospheric nuclear weapons testing. Levels such as these have besn observed in vegetation samples taken from farms near the plant during previous operational periods (7-23).

D.4 External Radiation i Thermoluminescent dosimeters were collected monthly from twenty-three locations surrounding the plant. The locations are On Site Along the Cliffs (sample code DRl), Route 4 Auto Dump (sample .

code DR2), Giovanni's Tavern (sample code DR3), White Sands (sample code DR4), John's Creek (sample code DR5) , Lusby (sample code DRC), On Site (sample codes DR7 (OLD) and DR7(NEW)--see .

section C.4 Program Exceptions and Table A-1 in Appendix A for an explanation of this sample coding), On Site Near the Emergency Siren (sample code DR8), Bay Breeze Road (sample code DR9),

Decatur and Calvert Beach Roads (sample code DR10), Dirt Road off Mackall and Parran Roads (sample code DR11) , Mackall and Bowen .

Roads (sample code DR12), Wallville (sample code DR13), Rodney I Point (sample code DR14), Mill Bridge and Turner Roads (sample  :

code DR15), Appeal School (sample code DR16), Cove Point and '

Little Cove Point Roads (sample code DR17), Cove Point (sample

  • code DR18), Long Beach (sample code DR19), On Site Near Shore  ;

(sample code DR20), Emergency Offsite Facility (sample code DR21), Solomons Island (sample code DR22), and Taylors Island  !

(sample code DR23).

A comparison of the means and ranges of the current TLD data with those of both the historical data and the regional data shows that a plant-related contribution to the measured exposure rate  !

was not discernable.

E. Conclusion Low levels of various man-made fission and activation by-products  !

were observed in the environment surrounding the plant during the '

year 1987. Some of these observations were attributed to fallout  !

from past atmospheric weapons testing. The others cited were 3 related to the operation of the plant (viz., H-3, Co-58, and [

In order to assess the plant's contribution to the ambient radiation levels of the surrounding environment, dose calcula-tions were performed using the plant's effluent release data, on site meteorological data, and appropriate pathways. The results of these dose calculations indicate:

o Gaseous Pathways A maximum thyroid dose of 1.61E-01 mrem to an infant via the plume, ground, and inhalation pathways at the on l site location 0.3 km north of Calvert Cliffs, which is about 0.2% of the acceptable linit of 75 mrem / year as specified in 40 CFR 190, "Environmental Radiation Protection Standards for Nuclear Power Operations".

A maximum whole body gamma dose of 1.44E-01 mrem at the on site location 0.3 km north of Calvert Cliffs, which is about 0.6% of the acceptable dose limit of 25 l

, mrem / year as specified in 40 CFR 190.

A maximum dose to any organ, in this case skin, of 4.26E-01 mrem at the on site location 0.3 km north of Calvert Cliffs, which is about 2% of the acceptable dose limit of 25 mrem / year as specified in 40 CFR 190.

o Licuid Pathways l

A maximum thyroid dose of 2.20E-01 mrem, which is about 0.3% of the acceptable dose limit of 75 mrem / year as specified in 40 CFR 190.

A maximum whole body dose of 1.06E-01 mrem via all liquid pathways, which is about 0.4% of the acceptable dose limit of 25 mrem / year as set forth in 40 CFR 190.

A maximum dose to any organ, in this case the GI tract, of 9.35E-01 mrem, which is less than 4% of the acceptable dese limit of 25 mrem / year as specified in 40 CFR 190.

I o Gaseous and Liquid Pathways Combined

{

A maximum thyroid dose of 3.81E-01 mrem via liquid and gaseous pathways, which is about 0.5% of the acceptable limit of 75 mrem / year as specified in 40 CFR 190.

. 9 G

January 1 - December 31, 1987 Docket Nos. 50-317/318 -

A maximum whole body dose of 2.50E-01 mrem via liquid and gaseous pathways which is about 1% of the acceptable limit of 25 mrem / year as specified in 40 CFR 190.

A maximum calculated dose to all other organs ~via liquid and gaseous pathways was equal to 1.36 mrem from the GI tract and skin, respectively. This dose was about 5% of the allowable limit of 25 mrem / year as specified in 40 CFR 190.

In all cases, the calculated doses are a small fraction of the '

applicable limits specified in 40 CFR 190. On this basis it is concluded that the operation of Calvert Cliffs Units 1 and 2 met the criteria'of 40 CFR 190 during 1987.

In addition it is also concluded, based upon the levels of radioactivity observed and the various dose calculations per-formed, that the operation of Calvert Cliffs Nuclear Power Plant Units 1 and 2 during 1987 did not cause any significant impact on .

the environment.

A detailed description of the Land Use Sursey is given in a separate document (36). The position of the nearest dairy cow, residence, and garden in each sector up to 8 km are given in the above table. The closest residence and garden are situated in the WSW sector, which is one of the least prevalent wind directions. In the S, SSE, and SE sectors there is the highest probability of wind blowing from the direction of the plant. The two gardens used for vegetable samples by the Radiological Environmental Program have been placed in the sectors with the highest X/Q. One sampling garden is located in the S sector at a distance of 0.7 km, and another is situated near the site boundary between the SSE and SE sectors at a distance of 2.6 km from the plant. These two sampling sites are considered good indicator locations for radioactive depositions around the plant. There are no sites identified in the Land Use Survey that show a greater dose commitment than those sites currently being sampled. The dose assessment using 1987 meteorological data was performed, and no' . significant impact from the operation of the plant was found. T e 67 l e
